Residual Marshall Stability, Aggregate Characteristics, Lajjoro RiverAbstract
River stones from the Lajjoro River, Palakka Subdistrict, Bone Regency, are commonly used as house foundations, but their potential for AC-BC pavement mixtures was investigated. This study aimed to determine their compliance with Bina Marga 2018 Specifications. Conventional Marshall and Marshall Immersion tests were performed in the Asphalt Laboratory to analyze their performance. Results showed that stability, flow, VFB, VIM, and VMA met the requirements at 5.0%–7.0% asphalt content. The maksimal asphalt content was 6.5%, with the highest stability of 1907.85 kg and a residual Marshall stability (SMS) of 92.70%, indicating strong durability. These findings confirm that Lajjoro River stones are suitable for AC-BC mixtures, providing a reliable alternative for road pavement applications while utilizing local materials efficiently.
